    Wastes connected with zinc and lead industry are extremely harsh substratums for plant growth. They contain high levels of heavy metals, lack organic matter and are characterized by low porosity resulting in unfavourable air-water conditions (Fragment tekstu)

    This is an accepted manuscript of an article published by Elsevier in Ecological Engineering on 05/08/2016, available online: https://doi-org.ezproxy.wlv.ac.uk/10.1016/j.ecoleng.2016.06.029 The accepted version of the publication may differ from the final published version.The aims of this studies were: (i) to examine the influence of heavy metal content (Zn, Cd, Pb, Fe, Cu) and other physico-chemical soil parameters on the level of root colonization of Molinia caerulea and (ii) to relate root colonisation parameters and soil variables to Molinia caerulea abundance in two contrasting habitats (grasslands and heavy metal contaminated sites). The sites differ significantly in terms of bio-available heavy metal contents, particularly Zn (34 times more than grasslands), soil texture, CaCO3, organic matter (LOI%), Mg and nitrate content. Principal Component Analysis showed the strong negative correlations between frequency of mycorrhization (F), arbuscular abundance (A%) and intensity of root cortex colonisation (M%) and concentration of bio-available Zn and Cd. Moreover, no positive correlation between root colonization of Molinia and its abundance was found. The frequency of mycorrhization of root fragments (F%) was only slightly different between these two habitats, whereas the intensity of root cortex colonisation (M%) and relative arbuscular abundance (A%) were significantly lower (3 and 4 times respectively) on the post-industrial sites. The bioavailable Zn content in the substratum of post-industrial sites was strongly negatively correlated with species richness, Shannon diversity index and Evenness. In contrast, these relationships were not statistically significant in grasslands. Based on obtained results we could draw a model of possible relationships between root colonization of Molinia, HM content and Molinia abundance on grasslands and post-industrial sites. Bioavailable Zn content in the soil is a one of main factors influencing the Molinia community diversity. In the grasslands, lower amounts of bioavailable Zn, resulted in higher species richness (R) and species diversity (H) which in turn lead to higher root colonization. On the other hand, on the post-industrial sites, the elevated bioavailable Zn content strongly decreases the plant species richness (R) and species diversity (H) and this caused the decline in root colonization parameters. The low species richness on Zn-polluted sites allowed Molinia to reach higher abundance since the competition with other species is reduced

    Our IPRO is called Edutainment because we develop computer games that educate and entertain at the same time. The goal for IPRO 329 is to complete a 3D financial aid computer game – College Pursuit – as well as start a children’s game – Scholars of the Lost Exhibit. In College Pursuit, students accumulate money towards college via scholarships, grants, and loans. Scholars of the Lost Exhibit takes the student on a journey through a magical museum filled with friends and foes, while testing the student in the areas of Math, Science, Social Studies, and Language Arts.Deliverable

    Solar/Wind Hydrogen Fueling Station at IIT (semester?), IPRO 304B: Solar Wind Hydrogen Fueling Station IPRO 304B Poster Sp05

    The objective of this project is to design a renewably powered hydrogen fuelling station at IIT to be part of the Illinois Hydrogen Highway. Based on past recommendations a project site will be selected for the fuelling station. This site will also include a wind turbine and solar panel array to capture renewable energy. The principles of process design will be used to layout hydrogen production, storage, and implementation of renewable energy technologies. The stations will meet all local codes for hydrogen storage, production, and usage. This station will be designed in conjunction with the House of the Future, which is part of IIT’s Sustainable Village.Deliverables for IPRO 304B: Solar/Wind Hydrogen Fueling Station at IIT for the Spring 2005 semeste
